Product Details
Product Features
PTFE and PVDF materials have good corrosion resistance, high temperature resistance and wear resistance, and can be used in all situations of concentrated acid and concentrated alkali, including HF and fuming nitric acid (concentration of 9896) and so on.
Product Characteristics
1、PTFE bearing is the best corrosion resistance of all known engineering plastics, almost insoluble in a solvents, water absorption and fiction coefficient is very low, wear resistance is very good, anti-aging, flame retardant, insulation is excellent. but the mechanical strength of PTE material is very low.The coefficient of linear expansion is large
2、PVDF bearing has excellent resistance to chemical corrosion, high mechanical strength,hardness and toughness, aging resistance, radiation(ultraviolet, β -ray, y *ray), good dimensional stability. But the coefhcient of linear expansion is large and processing is not easy.
